BUCKLE.

SPECIFICATION forming part of Letters Patent No. 249,510, dated November15, 1881.

Application led July 18,1881. (No model.)

To all lwhom it may concern Be it known that we, CHARLES E. DRURY andALLEN C. VAN CAMP, of Girard, VErie county, Pennsylvania, have inventednew and useful Improvements in Harness-Trace Buckles and we do herebydeclare that the following is afull, clear,.an d exact descriptionthereof,

reference hein g had to the accompanying drawings and letters or figuresof reference marked thereon. I

Our invention` relates to the construction of harness-trace buckles; andit consistsin certain new and useful improvements thereon, as willhereinafter fully appear.

In the accompanying drawings, Figure l is a perspective view of thebuckle. Fig. 2 is a horizontal transverse section on the line Fig. l,with the trace and haine-tug shown.

A A, te., are the sides or frame ofthe buckle; A', the back or web ofthe frame-work B, the presser or clamp; B', a handle for operating thepresser. a. a are grooves in the sides A, in which the presser or clampslides. b is a stop on'the presser, and c care stops on the frame, whichprevent the presser leaving the grooves a a'when loosened, so as toallow the tug or i trace to move. `'l is the tug or trace; H, thellame-tug, and s s 's are serrations on the inner slde of the clamp orpresser.

Therug or nace is held by this buckle byj pressure, and not by a tongue,as commonly. We do not, however, lay claim to this feature of ourdevice, for it has been done in many forms of buckles.

The frame A and back orweh A' are of one piece of metal, and has thegrooves ci a formed therein in any convenient manner-as, for example, hyheilig milled or cut by a milling-machine, or by being formed in thecasting when molded. It will he observed from thedrawin gs that thegrooves are not parallel with the hack A', but approach it as th ey gohack. The presser B slides freely in the grooves a, and enters them,when pnt in place, from the rear, and is shoved forward far enough toallow the tug 'l t0 be slipped in from the same direction. The lugs band c prevent the presser from leaving the frame in front when pushedthat way to loosen the tug. The knob or handle B' is to facilitate themovement of the presser in loosening the tug. The presser has its facewhich comes in contact with the tug roughened or serrated, so as toprevent the tug slipping he neath it; but the serrations s s s shouldnot be sharp enough to cut the leather ofthe tug.

The manner in which the tug is clamped is plainly shown in Fig. 2. Themore strain there is upon the tug the harder the presser or clamp B ispressed against it on account of the inclination of the grooves c. Toloosen the tug the presser is pushed forward by pushing on the knobfB'.

That we claim as new is- In a harness-trace buckle, the frame A, withgrooves a. a opening at the rear of the frame, and having stoplugs c cat the front of the frame,in ccmbination with a presser, B, whichslideswithin said grooves and enters the same from the rear, and is providedwith stoplugs b, which engage with the stops c c and prevent the presserfrom escaping from the grooves, all substantially as and for thepurposes mentioned.

In testimony that we claim the foregoing we have hereunto set our hands.
